Some huge stumps and logs pulled from Grand Lake near the St. Marys Boat Club sit on top of a barge. State employees began removing stumps from the lake on Tuesday and will continue the project for at least two weeks and maybe longer if necessary, said Grand Lake St. Marys State Park Assistant Manager Brian Miller. Workers this week also pulled from the same area a long, steel pipe that is believed to have been left over from the lake's oil derrick days.
